INSERTION FLOW METERANALOG OUTPUT
DESCRIPTIONONICON insertion turbine flow meters are suitable for measuring electrically conductive water-based liquids. The FB-1210 model provides non-isolated 4-20 mA and 0-10 V analog output signals that are linear with the flow rate as well as a binary (digital) dry contact output for flow direction.
APPLICATIONS• Primary/secondary decoupling loop (bypass)• HVAC thermal storage tank• Domestic water tank charge/discharge

CALIBRATION
Every ONICON flow meter is wet calibrated in a flow laboratory against primary volumetric standards that are directly traceable to N.I.S.T. A certificate of calibration accompanies every meter.
FEATURES
Unmatched Price vs Performance - Custom calibrated, highly accurate instrumentation at very competitive prices.
Excellent Long-term Reliability - Patented electronic sensing is resistant to scale and particulate matter. Low mass turbines with engineered jewel bearing systems provide a mechanical system that virtually does not wear.
Industry Leading Two-year “No-fault” Warranty - Reduces start-up costs with extended coverage to include accidental installation damage (miswiring, etc.) Certain exclusions apply. See our complete warranty statement for details.
Installation Flexibility - Patented dual turbine models deliver outstanding accuracy in short pipe runs.
Simplified Hot Tap Insertion Design - Standard on every insertion flow meter. Allows for insertion and removal by hand without system shutdown.
